The development of bacterial endocarditis as a result of endoscopic interventions within the gastrointestinal tract is exceedingly rare. Antibiotic prophylaxis for endoscopic procedures is generally not warranted, except for certain high-risk patients. Double-balloon enteroscopy (DBE) is a common endoscopic procedure for evaluation of the small bowel. Bacterial endocarditis secondary to DBE has not been previously described. We describe the first case of enterococcal endocarditis attributed to DBE in a patient with a history of stage 1 primary biliary cholangitis.
